Synchronous drive belts are used in driving car engine camshafts and other mechanisms. Load was measured on each tooth root of a cam pulley engaged with a synchronous drive belt with rounded teeth used with a four-cycle gasoline engine, and then was the dimensionless load distribution ratio calculated by dividing the tooth root load distribution by the belt tension load. Thus, the relationship between the distribution ratio with engagement position load and the belt tension load was analyzed. As the result of this study, the following conclusion reached : When material properties, tooth profiles and other specifications are the same, under both dynamic and static loads, the tooth load distribution ratios of pulleys with rounded teeth used to drive engine camshafts are almost the same as the speed range adopted in the operation of production car engines.
